Q

Stabilizer Trim System

Displays actual stabilizer position in ____ increments from ____ to _____ units of trim flaps down on the ground, and _____ to _____ units flaps up and in the air.
Corresponding pointer position is shown on the ND/NU (nosedown/nose up) scale.

A

Displays actual stabilizer position in 0.25 increments from 0.25 to 16.75 units of trim flaps down on the ground, and 1.50 to 16.75 units flaps up and in the air.
Corresponding pointer position is shown on the ND/NU (nosedown/nose up) scale.
